To discuss characteristics of height growth such as Peak Height Velocity (PHV) and Age at Peak Height Velocity (PHA) during adolescence, and to compare the results with other research findings.
Primary and middle school students' annual physical examination data of Zhongshan in 2005 - 2010 was used. The height velocity by age, PHV, PHA, height velocity by PHA were calculated.
The average peak height velocity boys was (10.03 ± 1.67) cm/yr. and that of the girls was (8.39 ± 1.05) cm/yr. Both findings were close to the results from previous similar findings. The average age at which peak height velocity reached 12.28 ± 1.30 years for boys and 10.78 ± 1.04 years for girls, both lower than the previous findings. The correlation coefficients, between height level and PHA were -0.357 (P < 0.001) for boys and -0.338 (P < 0.001) for girls.
The height levels were positively related to the height velocity before PHA. The Zhongshan students' PHA was lower than the Beijing, Shanghai and Shenyang students, also lower than American and Britain students', but their PHVs were similar.
探讨青春期身高增长的特征,如身高生长高峰速度(PHV)和身高生长高峰年龄(PHA),并将结果与其他研究结果进行比较。
使用2005 - 2010年中山市中小学生年度体检数据。计算各年龄的身高速度、PHV、PHA、PHA时的身高速度。
男生平均身高生长高峰速度为(10.03±1.67)厘米/年,女生为(8.39±1.05)厘米/年。这两个结果均接近先前类似研究结果。身高生长高峰速度达到时的平均年龄,男生为12.28±1.30岁,女生为10.78±1.04岁,均低于先前研究结果。男生身高水平与PHA之间的相关系数为-0.357(P<0.001),女生为-0.338(P<0.001)。
身高水平与PHA之前的身高速度呈正相关。中山市学生的PHA低于北京、上海和沈阳的学生,也低于美国和英国的学生,但他们的PHV相似。
